This new cooler has been running for several hours now. It runs under normal load at a quiet hum under 4-pin PWM control and seems to be keeping the CPU at a very stable temperature after my last cooler (different model and make) failed on me. It's quite a sturdy build, aesthetically pleasing to look at for those of you who like side windows in their cases. Connections between the parts of the cooler seem cushioned to reduce vibration noise to a degree of care I haven't seen in other similarly priced coolers. My one issue was with the fitting. Every CPU cooler I've used in the past have been of the kind that use a locking lever to secure the cooler to the motherboard. This doesn't have that, and I'm sure it's to cut down on parts that may vibrate and increase noise levels. Instead it has two screws to loosen the brackets, then tightened to secure after it's been clipped to the motherboard. This was very fiddly as a repair job in a fully built PC and on my first attempt I didn't get a good seal with the thermal paste onto the CPU requiring a second attempt (which, depending on if you made a connection of some sort or not, would require a tube of thermal compound at hand). However, I got there in the end and this is my only negative remark about this cooler. It shouldn't be an issue at all on a newer build where I would suggest fitting the cooler early on when you have more room to work inside the computer case.
Overall, I'm very impressed especially considering the lower end price.
